Battery-electric variants have no combustion engine and take no engine oil. They do use reduction-gear fluid and coolant — check the handbook for whether either is a scheduled service item on your car.
Both engine families use the same 0W-30, PSA B71 2312 low-SAPS oil. Capacities vary by variant — confirm by VIN.
Not sure which engine you have? The required spec is on the oil filler cap; the engine code is in section D.2 of your V5C.

Why Your C4 Needs PSA 0W-30 (B71 2312)
The C4’s 1.2 PureTech petrol and 1.5 BlueHDi diesel engines use 0W-30 oil to PSA B71 2312, a low-SAPS oil protecting the DPF and the PureTech wet belt. Always match 0W-30 + PSA B71 2312, not a generic 5W-30.
Oil Change Intervals
Stellantis intervals are ~12 months or up to 16,000 miles; many specialists advise changing the PureTech more often (every 6,000–9,000 miles) to protect the wet belt.
Tip: always fit a new filter with the oil.

How we check fitment for this guide
We cross-reference fitment figures against manufacturer specifications and OE-supplier catalogue data where available, and matched to the standard codes that actually govern fit — battery type/group sizes, wiper lengths and fitting types, bulb fitment codes, tyre size markings, and oil specifications. We work by make, model, year, engine, and build date, because a single model can take different parts across its life. Where the right part depends on your exact vehicle, we tell you to confirm by registration or VIN. More on our method →
